Radiological Evaluation of Femoral Head Osteonecrosis in Patients with Sickle Cell Disease

Abstract

Background and Aim: Osteonecrosis of the femoral head (ONFH) is a severe complication in
sickle cell disease (SCD), often leading to joint collapse and disability. Early identification of
epidemiological, clinical, and radiological features is crucial to guide management and improve
outcomes.
Material and Methods: A retrospective study was conducted at a tertiary care hospital in India
including 30 SCD patients. All patients underwent pelvic X-rays, and MRI was used when X-rays
were inconclusive. Lesions were staged using the ARLET and FICAT classifications, and data
were analyzed by age, radiographic stage, and genotype.
